This means disconnect the large hose. Then plug the line to the exhaust
manifold so that exhaust gas will not back up into the system that is not
designed
for those temperatures. Then you adjust the CO reading to the specified
level.
You would be interested to see the CO level drop significantly after the air
system is restored. I was.
